MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 245,426, dated August 9, 1881.

Application filed September 3, 1880. (No model.)

To all whom it may concern:

Be it known that I, OLIVER H. ARNO, of WVilmington, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Mechanical Musical Instruments, of which the following is a full, clear, and exact description.

This invention relates to mechanical musical instruments which are operated by a perforated 1o sheet of paper or other suitable material.

Usually in the operation ofsueh instruments two rolls are used for the sheet material, one on which it is wound previous to being run through the instrument, and from which it is unwound in the operation of the instrument, and called the 1n usic-roll, and the other, on which the sheet material is wound during the operation of the instrument, called the takenp roll.

This invention is illustrated in the accompanying drawings, in which Figure l is an end view of a take-up roll and feed-rolls of a mechanical musical instrument having this invention attached thereto. Fig. 2 is a plan view;

2 Fig. 3, a view in end elevation, and Fig. 4 a

vertical section on line or m, Fig. 2.

In the drawings, A represents a frame-work supporting and carrying the various parts; B and O, two feed-rolls, the shaftD of the one, O,

0 being the driving-shaft and operated by the crank-arm E, or in any suitable manner; F, the take-up roll.

The feed-rolls B and O and the take-up roll F are constructed as usual for such rolls in me- 5 chanical musical instruments, the perforated sheet N being fed by the feed-rolls through the instrument and then wound upon the takenp roll.

On the driving-shaft D is a geanwheel, Gr,

which gear-wheel engages with another similar gear-wheel, H, below it.

On the shaft to of the gear-wheel H is a pulley, J, which pulley is connected bya belt, K, to another pulley, L, on a horizontal shaft, M,

5 turning on its journals Z) in the frame A.

The take-up roll F turns by itsjournals c in the vertical slots (1 in the frame A, and is com posed of a spindle, f, havin g on each end a circular flange or rim, g.

The music-sheet N is attached by one end to the spindle f, and in the operation of the instrument the take-up roll is turned, and as it.

turns the music-sheet is wound on the spindle between the flanges or rims 9.

On the shaft M are two bands or rings, 0, of india-rubber or any suitable elastic material.

The take-up roll when in position in the instrument, itsjournals in the slots (1, rests by its flanges g on the elastic rings or bands 0 of the shaft M, so that by turning this shalt the take up roll, through the friction of the elastic rings 0, will be turned and the sheet material wound thereon. Turning the driving-shaft operates thefeed-rollsand feeds themusicsheet through the instrument, and by the gear and belt 0011- nection herein describedthe shaftMis revolved, and throu gh the frictional contact of the flanges of the take-up roll on the elastic rings 0 the take-up roll is caused to turn and the musicsheet wound thereon. As the perforated sheet material winds upon the take-up roll, as above described, in the operation of the instrument, the said sheet material increases in thickness and diameter on the spindlef, and such increase causes the sheet material to travel fast- 7 5 er from the feed-rolls than the feed-rolls deliver it, and in such case the sheet material must either break or be pulled through the feed-rolls or stop the instrument; and to obviate such troubles is the object of the present in vention, and which is accomplished as follows:

In the operation of the instrument, as the sheet material between the feed-rolls and the take-up roll becomes taut, by reason ot'the winding of it faster on the take-up roll than delivered by the feed-rolls, such tautness will cause the take-up roll to rise from its bearing on thefrictional driving-bands O,freein g and disconnectingitselftherefrom,whieh movement is allowed by the journals 0 of the taken p roll be 0 ing located and turning in the slots (1, obviously stopping the turning of the take-up roll, and consequently cease the winding ofthe sheet material thereon until a su'tficient length of the sheet material is delivered from the feed-rolls 5 to allow the take-up roll to fall and rest upon the frictional bands 0 again, when it will again be turned and the music-sheet wound thereon again, and so on until the whole length of sheet material is wound on the take-up roll, as desired.

The roll can be raised from its bearings on the frictional bands for the purpose of unwinding the sheet material therefrom in any manner desired.

In lieu of having the slots d for the journals of the take-up roll in a vertical line, as shown, they can be inclined in either direction and accomplish like results.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a mechanical musical instrument adapt ed to be operated by a perforated music-sheet, the combination of a roll for taking up said sheet, a friction-roller on which the take-up roll normally rests, and by which it is rotated through suitable niechanism,said take-up being capable of rising in its bearing and freeing itself from the friction-roller by the action of the music-sheet, substantially as described.

. 2. Inamechanical musical instrumentadapted to be operated by a sheet of perforated material, the combination of a take-up roll adapted to risein its bearings, and having an annular flange at one end, a transverse shaft arranged below the take-up shaft, and provided with an annular friction-roller, on which the flange of the take-up roll bears and by which it is to be rotated, and a driving mechanism for rotating the shaft carrying the frictionroller, all substantially as described, for the purposes set forth.

3. The combination of the rollers for feedin g the perforated sheet, the take-up roll adapted to rise in its bearings, and provided with an annular end flange, a shaft arranged below said take-up roll, and provided with an annular elastic friction -rol1er, on which the end flange of the take-up roll rests and by which it is rotated, and mechanism connecting one of the feeding-rollers with the shaft of the friction-roller, substantially as described, and for the purpose set forth.

4:. In amechanicalmusioalinstrument adapted to be operated by a sheet of perforated material, the combination of a friction-roll, 0, ar-

ranged on a shaft, M, a pulley, L, at one end of said shaft, a belt, K, a pulley, J, on the shaft of one of the feeding-rollers, and a takeup roll resting on the friction-roll and adapted to be automatically raised from contact therewith by the action of the music-sheet, all substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
